/* emobfus - email address obfuscation
 * By Justin Force <justin.force@gmail.com>
 * Modified Jul 14, 2009
 * Requires Prototype >= v1.6 <http://prototypejs.org>
 *
 * Email addresses should appear in the document as follows
 * <span class="emobfus">domain.tld joe</span>
 *
 * They will be reassembled as
 * <span class="emobfus">joe@domain.tld</span>
 *
 * The script isn't picky about whitespace. <span ...>     company.com
 * joe</span> is ok.
 *
 * If you instead set the class to emobfusl, a mailto: link will be inserted as
 * well, i.e.
 * <span class="emobfusl"><a href="mailto:joe@company.com">joe@company.com</a></span>.
